COOLING-BOARD.

, TSPE'GIFICATION forming part of Letters Patent No. 434,443, dated August 19, 1890.

Application filed Jimm 9,1890. Serial No. 386,440. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM A. GRIFFITH, of Milwaukee, in the county of Milwaukee and State of WVisconsin, haveinvented new and useful Improvements in Cooling-Boards;

and I do hereby declare the following to be a full, clear, and exact description'of said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forma part of this specification.

My improved cooling-board isadapted for use for receiving thereon the bodies of children or of full-grown persons, andis provided with certain new features, which make it more convenient for use and obviate the necessity for a number of boards of different sizes.

In the drawings, Figure 1 is a longitudinal vertical section of my improved device. Fig.

2 is a plan view of the same device, the canopy being removed. Fig. 3 is a transverse vertical section of the device shown in Figs. 1 and 2 on line X X of Fig. 1, looking in the 2 5 direction of the arrow, but without the canopy. Fig. 4 is a detail of the head rest and the means by which it is made adjustable.

A frame A is supported at one end by the thereto-hinged legs B B and at'the other end by the thereto-hinged leg 0, and a frame A is supported atits outerendbythe legs B B, and at its other or inner end itis supported on the inner end of the frame A, the two frames Aand A being so constructed that the one slides 5 on the other, whereby the frames are telescoped, and the entire board is capable of being drawn out and pushed together, as desired.

The legs B B and B B are preferably so constructed and hinged to the respective frames that when opened out they will stand in inclined or bracing positions, as shown in Fig. 1. These legs are each provided with a spring-catch D, affixed to the leg and provided 5 with an aperture adapted to catch onto apin in the frame, whereby the catch is made to serve the double purpose of a stay-rod or catch and a brace. The leg 0 is also provided with a similar spring-catch D, and all these legs are adapted to be temporarily folded down within their respective frames A and A. In the construction shown in the drawings the side pieces of the frame A are each provided with a longitudinal dovetailed groove, in which the dovetailed guides E E of the frame A are adapted to travel, the inner end of the frame A being supported movably on'the guides E E.

The frames A and A are each provided with open-work cane tops, the top of the frame A being divided into two parts F and F, the part F being hinged to the part F, so that its outer or head end is adapted to be raised and lowered, as indicated by the construction shown in Figs. 1 and 2. The part F is supported adjustably in a less or greater inclined position by swinging arms G G, pivoted thereto, the free ends of which are adapted to enter .notches in the racks H H, affixed to the frame A. The part F is secured perma-nently to the frame A, but projects beyond the end of the frame A over and covers the frame A for adistance from the line of junction of the frames A and A, the two parts F and F forming a continuous top of suflicient length to receive thereon the entire body of a person, the lower limbs only, in the case even of the longest person, extending beyond the part F onto the cover or top of frame A.

A head-rest consisting of a ring I is pivoted centrally at its twosidesin the bifurcate arms of a standard K, the shank of which standard is inserted in an aperture therefor in the frame of the part F, near its outer-end, in which aperture the standard Kis adapted to rotate laterally, and also in which it is adapted to be adjusted vertically and held in position by a spring-actuated bolt L, having an end formed to enter undercircular shoul- 9o ders M M about the shank of the standard, whereby the standard is supported at any height to which it is raised. For a stronger and better construction a bushing N is inserted in the aperture about the shank of 5 the standard K. It will be noticed that this head-rest has a tilting movement of the ring I, a laterally-swinging movement of the standard K, and a vertical adjustable movement of the standard in the part F of the frame A.

An aperture 0, sufficiently large to permit the passage of the hands therethroug'h, is

made in the part I of the frame A, near to and a little in front of the head-rest, whereby convenient opportunity is offered for man ipulation of the body thereon through this aperture. The upper surface of the frame A, including the parts F and F, is somewhat inclined from the outer head end downwardly to a thin and final termination, as shown in Fig. 1. I also provide a canopy for use in connection. with the cooling-board, which is removably connected therewith and made a part thereof. Four posts P P are supported upright in brackets R R, which brackets are affixed to the outer corners of the frames A and A. Two bands S Sone at each side are stretched from the head to the foot, which bands are each provided with a series of ap ertures 'l '1, into which the top ends of the posts P I are received, the bands resting on shoulders of the posts, whereby they are supported. ()ver those supporting-bands S S is placed the cloth canopy, constructed in two parts U U, adapted to overlap each other centrally, which overlapping will be greater or less as the two parts A and A of the frame are drawn out or telescoped together. It will be understood that the apertures T T in the bands S S provide for their being shortened up or lengthened out, as desired, to conform to the adjusted length of the cooling-board.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. I11 a cooling-board, the combination of a frame A, provided with an open-work top and supported on folding legs, of a frame A, supported at one end on folding Legs and at the other end supported on and arranged to slide and telescope in the frame A, and an openwork top formed in two parts, one part F of which is secured permanently to the frame A, and projects therefrom beyond the line of junction of the frames A andAabove and covers a part of the frame A, the other part F of which top is hinged to the part F and is capable of being raised and supported at one end in an inclined position and is provided with a head-rest and an aperture 0 near the head-rest, substantially as described.

2. In acooling' board, a tilting frame F, provided with a head-rest and an aperture 0 therein, located and constructed substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM A. GRIFFITH.
